Chamberlainia stereopoma (Spruce ex Mitt.) H. Rob.
Brachythecium stereopoma is a robust moss with a weak costa that does not reach the apex. The alar cells are not bloated but rather are relatively thick walled. The leaves are over a millimeter long and are straight and plicate. The leaves are serrulate and very cup shaped (concave.) Because they are so concave, when they are stripped from the stem to prepare a slide with a cover slip, they tend to be folded or longitudinally slit. They are rather oval shaped for the genus and have an abruptly acuminate tip. Brachythecium stereopoma lives in the forest at higher elevations.
